"A moment ago This company is great. Roy Villa the service technician was very knowledgeable. No threat of up selling. Just explained what was wrong with the heating system and fixed it. This is for a rental house. He told me about the warranty plan they have for heating and AC. It was extremely reasonable. Now I will just have the AC and heater checked before each season."

"We hired Airmercia Air Conditioning & Heating to evaluate our heating system and propose repair solution. Ryan was very professional and punctual. He did not make any force sales. He just offered various repair and replacement solutions and explained pros and cons for each one. We decided to replace our furnace and duct system. Ryan did an excellent Job!! I highly recommend him for your HVAC project."

"I had been told by another company that my HVAC unit needed to be replaced for $3500.  However, the technician didn't even look at the unit.  So I subscribed to Angie's list and chose Liberty for a second opinion.  Apparently all that was needed was to add coolant; the level was very low.  My AC is now working better than ever.  Thank you Liberty and Angie's list for saving me over $3000!

"Technician Angel came on time. He first cleaned our HVAC unit, checked the wirings & parts & performed tests to ensure the unit is running according to standards. He inspected the Air ducts, vents even the attic. He explained everything and showed us the pictures that he took & the results on HVAC heating and cooling tests that were done. Overall a very good job done by Technician Angel I told him to come back after 6 months. Already recommended Airtime Heating & Cooling to my neighbor. 5 STARS"

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

Heating and Air Conditioning questions, answered by experts

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.
